Guide wheels
Bishop- Wisecarver Corp., Pittsburg, Calif. |
 DualVee
guide wheels are available in two new sizes, size 0 and size 4XXL, respectively
larger and smaller than the previously available sizes, W1 through W4. Size
0 has an outside diameter of 0.58 in. and a working radial load capacity
of 62 lbs., while size 4XXL has an outside diameter of 2.97 in. and a working
radial load capacity of 1,620 lbs. The guide wheels are constructed of elements
manufactured from 52100 bearing-grade steel. Hardened to Rockwell 60, the
balls and raceways are protected from the ingress of debris by a pair of
nitrile rubber seals, and a retainer maintains ball separation. The precision
raceways are ground directly into the inner and outer race of the guide
wheel to maximize stiffness and running accuracy. The new guide wheels are
also available in stainless steel, providing for a higher level of corrosion
resistance. The stainless steel version of the size 0 wheel is categorized
as clean room compatible. It has load-bearing elements made of 440C stainless
steel and is lubricated for life with a specially formulated PTFE Krytox
grease. Shields and retainers are made of 304 stainless steel.

Capillary saturation porometer
Porous Materials Inc., Ithaca, N.Y. |
 The capillary
saturation porometer determines pore volume without using mercury and also
measures liquid permeability. The sample is soaked in a liquid that spontaneously
fills the pores in the sample. The pressure of a nonreacting gas on the
top of the sample is increased to displace the liquid from the pores. The
volume of displaced liquid from the pores is measured. The pore diameter
is obtained from pressure. Pore volume, diameter, and volume distribution
are computed. To measure liquid permeability, pressure on the liquid maintained
on top of the sample is increased, the volume of liquid flowing out of the
sample is measured, and liquid permeability is computed.
